N64 Compression
« on: March 22, 2017, 03:54 AM »
This topic was brought up in the Translation thread, and I thought it might be good to give N64 compression its own thread.  Feel free to share your experience below and any programs that you use along with instructions on how to use them.  I'll try to organize it all in this main post.


MidwayDec by Zoinkity

  Pros: It decompresses just about everyhing out there.  It requires a "filelist" for each ROM it decompresses which basically points to the location and tells it how to extract/decompress the file.  The program comes with some helpful documentation and about 400 "filelists".

  Cons: Midwaydec does NOT however give any options to recompress or reinsert the files back into the ROM.


Yaz0enc/Yaz0dec by shevious/daegunlee

  Pros: Drag and drop the ROM onto the yaz0dec file and it searches through every byte of the game to extract/decompress all Yaz0 files.  Drop a decompressed file on the yaz0enc file to encode it.

  Cons: You have to reinsert the file on your own.  If there are a lot of Yaz0 files, sorting through them can be difficult.

  Other: Two modified versions by ozidual.
    1. yaz0decCombined - Combines all of the files into one large file
    2. yaz0decSplit - Extracts all of the files, but also numbers them and lists their location in the combined file


N64 Rom Decompressor

  Pros: In Zoinkity's own words, it's better than midwaydec.

  Cons: I don't know anything about it.

Thanks, that one looks/works very promising. It's nice to see it even got an option to inject files back to the rom. Now if only file identification was easier and less time consuming....

Used it for the Majora's Mask patch as well actually, bit of manual work afterwards to fix some things though.
